Heating Zone Length
  • Two heating zones: 195 mm for each zone, total  390 mm length
  • Constant temperature zone: 250 mm within +/-5oC. ( if two zones at same temperature )
Heating Elements

Working Temperature
Option 1: 1500ºC
Option 2: 1600°C
  • 16 pcs 1650ºC grade silicon carbide rod (12mm Dia. x 150mm heating  x  415mm length)
  • The rods are considered consumables and won't be covered by the warranty. Order more at the link above,
    • 1500°C Max for continuous heating.
    • 1600°C Max for < 1 hours heating.
  • 1650ºC grade Silicon carbide rod is very brittle, so it will be shipped separately from the furnace. Customers are required to follow our video instruction to install the heating elements by themselves.
   Option1                   Option2        
Temperature Controller &

  • Two 30 segments programmable PID digital temperature controller (click the pic to enlarge)
  • Two built-in S type thermocouple
Note: To achieve full computer temperature control, please use our MTS-02 control module.
We will install and test the control module before shipping, so we recommend you to order the module with a PC and let us configure the whole system for you. For more information, please click here.

Application Notes
  • The concept of continuous power feeding and processing can be realized by the use of Magnetic Fluid Sealed Swivel Coupling in line with Volumetric Feeder and Rotary Furnace. Please view the assembling approach diagram and video in below.  
  • For CVD coating, you may choose our multi channel Gas delivery system as Pic below right.
  • For CVD coating, you may choose our multi-channel Gas delivery system as Pic below right.
  • The tube furnaces  are designed for using under vacuum and low pressure < 0.2 bar / 3 psi / 0.02 MPa
  • Attention: A two-stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
